Indeed I do pay a DNS tax, and I did setup a proper SPF record (not DKIM since it is overkill/unreasonable: if your smtp server is pown, DKIM does not bring anything more than SPF as far as I can recall except complex kludge).
That said, SMTP was designed with the possibility to avoid the DNS tax: instead of a domain use [xxx.xxx.xxx.xxx] for an ipv4 or [IPv6:...] for an ipv6.
Where something seems really wrong: ppl removing my emails from their spam folder does not seem to have any impact.
